GANHO DE DESEMPENHO DO FEMA UTILIZANDO PROGRAMAÇÃO PARALELA E ÁRVORES DE PARTICIONAMENTO ESPACIAL

Processamento da Junção Espacial Distribuída utilizando a técnica de Semi-Junção Espacial

This paper presents a new Distributed Spatial Join algorithm with Semijoin technique in a scalable peer-to-peer platform. This technique reduces the network traffic and minimize the processing cost. Tests have demonstrated that the response time has been drastically reduced with the Distributed Spatial Join proposed in this paper. Resumo. Este trabalho apresenta um novo algoritmo de Junção Espa...

Impacto da Adoção de Tecnologia de Informação no Desempenho Organizacional Percebido utilizando o paradigma de modelagem de segunda ordem

Efeito do entrelaçador na comparação de desempenho de sistemas OFDM e SCCP

This article establishes a performance comparison between the OFDM (Orthogonal Frequency Division Multiplexing) and the SCCP (Single Carrier with Cyclic Prefix) systems from the interleaver point of view. Some interleavers schemes are analyzed in a block fading channel scenario, as well as in the context of deep fade static channels. Keywords— OFDM, SCCP, interleaving, frequency selective chann...

Contribuições em escalonamento e análise de desempenho de redes WirelessHART

Wireless Communication is a trend in the industrial environment nowadays and on this trend, we can highlight the WirelessHART technology. In this situation, it is natural the search for new improvements in the technology and such improvements can be related directly to the routing and scheduling algorithms. In the present thesis, we present a literature review about the main specific solutions ...

Comunidades de Investigação em Programação: Uma Estratégia de Apoio ao Aprendizado Inicial de Programação

This paper describes a research process that intends to develop a strategy to support initial programming learning. It is inspired in the theory of Matthew Lipman, as it was conceived through the redefinition of the concept of Learning Communities, to assist the students to maximize their learning through the conscientious evaluation of their level of self-efficacy, while they develop a better ...
